Heatpipes are among THE most important components of a modern heatsink, but not all heatpipes are created equal. Different wick structures affect heatpipe performance and if your heatsink has cheap heatpipes, the rest of the heatsink suffers.
The problem for consumers is that you can't see what's inside a sealed copper tube embedded in a heatsink. You simply have to trust what the manufacturer says is true. There's no way to see the wick structure on the inside of heatpipes without destroying a rather expensive heatsink in the process, so Frostytech did just that.
